DOE-2 is a widely used and accepted building energy analysis program that can predict the energy use and cost for all types of buildings. DOE-2 uses a description of the building layout, constructions, operating schedules, conditioning systems (lighting, HVAC, etc.) and utility rates provided by the user, along with weather data, to perform an hourly simulation of the building and to estimate utility bills.

eQUEST® is a sophisticated building energy use analysis tool that provides professional-level results. eQUEST was designed to allow to perform detailed comparative analysis of building designs and technologies by applying sophisticated building energy use simulation techniques.

Blower door test:
This is a standard diagnostic test to measure the air tightness of a building and gather information about overall infiltration and locate air leakages. This data is essential in analysing the energy efficiency of a building and determining the energy conservation strategy.

Infra-red thermography:
A thermography inspeciton uses an infrared camera to study the surface temperature of the building components and determine the heat loss patterns and possible causes of abnormal heat variation. This critical information is used to determine the overall energy management efficacy of a building envelope and target the remediation efforts.
